  If "defineProperty" trap is null or undefined, [[DefineOwnProperty]] call
  is properly forwarded to [[ProxyTarget]] (which is also a Proxy object).

  [[DefineOwnProperty]] (P, Desc)

  5. Let target be O.[[ProxyTarget]].
  6. Let trap be ? GetMethod(handler, "defineProperty").
  7. If trap is undefined, then
    a. Return ? target.[[DefineOwnProperty]](P, Desc).
